DOUBLE TELESCOPE BOX.

SPECIFICATION forming part of Letters Patent N0. 502,952, dated August8, 1893.

Application filed October 4, 1892.

.To all whom it may concern..-

Be it known that I, JOSEPH T. CRAW, acitizen of the United States, andaresident of J ersey City, in the county of HudsonjState of New Jersey,have invented certain new and useful Improvements in Double TelescopeBoxes, of

which the following is a specification.

My invention relatesto a new article of manufacture, to wit, a doubletelescope box,

that is to say, a box whereon the cover fits The box is' termed doublebecause for the first time in the history of the art the blank of whichit is formed is so cut, and scored that there are formed side and endflaps which turn down in clear to the bottom, thereby doubling the sidesand ends, and showing the same color and finish on the inside as on theoutside; and further, the bottom of the box is formed double, the insideflap showing the same color and-finish as the rest of the box. The sameconstruction is used with the cover, and thus I produce a double box (aswell as cover) every partof which is of a uniform color, finish andhandsome appearance, whereas heretofore, the inside and bottom of theboxes have exhibited the back of the board, which is of inferior colorand finish from the front. By my 4 pleted box in shape without the useof glues,

method of doublingthe thickness of the bottom, which I efiect by givinga very tight fitto the inner thickness of board, I give much additionalstiifness to the bottom of the box (or top of the cover) where stiffnessis most needed, and can therefire use lighter board for the sides'andends, thereby saving in the weight of board and cost of box.

My invention also relates to methods of construction such that theseveral fiapsof the box and cover shall interact upon each other asclamps and thereby hold the comcements, clips or any other fasteningswhatever.

Referring to the drawings which accompany-the specification to aid thedescription, Figure 1 is a longitudinal elevation of the box andcovercomplete. 'Fig. 2 is a perspective, partly broken, of the box,without the cover. This view clearly shows the relative positions of theseveral flapsin the'box after folding. Fig. 3 is a verticalcross-section on the line Serial No. 447,844. (No model.)

X-X of Fig. 2. Fig. 4 is a longitudinal vertical section on the line YYof Fig. 2. Fig. 5 is a-plan view on a much smaller scale of the blankout of which the box is made, and showing the various scores, cuts andflaps ready for folding. Fig. 6 is a plan view of the inside bottomclamp on the same scale as Fig. 5. Fig. 7 is a plan view of the blankout of which the cover is made, and showing the vari- 6o ous scores andcuts ready for folding. Fig.8 is a plan view of the inside cover clamp.Figs. 7 and 8 are on the same scale as Figs. 5 and 6. Fig. 9 is aperspective view on a scale between Figs. 2 and 5 of the box partlyfolded. Fig. 10 is a horizontal section as on the line Z-Z of Fig. 2,but on the scale of Fig. 9. Fig. 11 is a'plan view of a modified blank,wherein the bottom clamp is in the same piece with the rest of the box,and Fig. 12 is a vertical 7o cross-section of the box, made of thisblank. The scale is the same as Fig. 2. Fig. 13 is a plan view of amodified blank wherein the inside bottom clamp is in two pieces, eachpiece being connected with one side flap, and Fig. 14 is a verticalcross-section (on the scale of Fig. 2) of a box made of such blank.

Referring to Figs. 1 to 10 inclusive,a blank A, of paper board is takenand at a single operation is out on the external boundary lines So 1; 2,2; 3, 3; 4., 4; 5, 5; 6, 6; 7, 7; 8, 8; 9, 9p, 10, 10; 11; is alsocut'on the internal lines 12, 12; 13, 13; and is scored on the lines 14,15, 16, 16; 17, 17; 18, 1 8; .19, 19; 20 and 21. Thereafter an attendantplucks away the waste parts so as to leave the outline as described,separates the flaps on the aforesaid cuts, 12, 12, 13, 13, and breaksthe aforesaid score lines, 14; 15; 16,16; 17,17; 18,18; 10, 19; 20 and21. Thus there is produced a blank having the rectangular bottom flap,a," end flaps, b, I); turn down end flaps, c, 0'; inside end flaps, d,d, and e, e; side flaps,

f, f, and turn down side flaps, g,g In connection with these flaps it isespecially noted 5 that (first) the inside end flaps, d, d, e, e, areeach attached to one of the side flaps and are one-half as long as thebox is wide on the'inside; gsecond) that the turn down side flaps g, andg are each a very little shorter at each zoo end than the side flaps, f,f, the difference at each end being'the thickness of the board;

2o flaps, I), Z),

is of flaps, f, I", then folding in the inside end e, c, as in Fig. fl;folding down in the turn down side llaps, g, g, (which fold easily clearto the bottom of the box because of being shorter than the flaps, f,f,')

flaps rl I5 next folding up the end llaps, I), b, then folding down theturn down end llaps, c, 0', inside of the flaps, (1., d, e, 0',respectively, the said flaps, c, c, turning clean and easily over theflaps, d, (7,, c, 14, because of the end being a little wider (orhigher) than the side llaps, f,f. When so turned down in, said flaps, c,c, are pushed back and crowded between the edges, 5, 5, and 7, 7respectively of the flaps, g, g, and the liaps,d,

.25 d, e, e, respectively, and are here held bythe clamping action ofthe said flaps, g,g', Al said flaps, c, 0, being each a little higher,(or wider) than the flaps, b, b, bind on the bottom, (1. Thus by theaforesaid proportions 50 and relations of said flaps, b, b, e, e",d, d,

e,f, f, g, g, I provide a two-fold clamping action to hold the sides andends of the box in position. Finally the inside bottom clamp, 11, whichmay be made of heavier board, and a size to lit tightly within the boxall around, and has of course the upper side of the same color andfinish as the outside of the box, is put in and tightly clamps the turndown end and side [laps all around. This piece, 1', also manifestlystiifens the bottom of the box, which is the part where the pressure ofthe board comes, and gives efiicient strength even if the board belight. Also by reason of turning clear down and in the 3 flaps, c, c, g,g, and of the finished side of the flap, z, being up, the interior ofthe box has the same color and finish as the exterior,

which adds much to the neat appearance.

lhe cover is formed of a blank, B, with relatively the same cuts andscores as the box,

and in Figs. 7 and 8 the same letters and figures are applied to similarparts as in the foregoing figures. But as will be understood, the coverwillbe made a little larger in plan 5 than the box so as to telescopeover the same. Also, at the same operation with the cutting and scoringof the cover blank 13, (or at a separate operation) holes j,j, arepunched in said blank, 1;, being so positioned as to be in- 6o tersectedby the lines, 17, 17, so that when the blank is folded to form thecover, said holes, j, 7",become semicircular thumb notches, in each sideof the cover, as seen in Fig. 1. After the various flaps of the coverare folded, as described for the box, the inside cover clamp, 1., Fig.8, is inserted, thereby clamping the sides and ends of the cover allaround,

and also giving to thecover inside the same color and linish as it hasoutside In Fig. ll. is shown a blank wherein the doubling piece for thebottom, i, is formed integral with one of the side llaps, (g,) the line(i being new a score line. In allotherrespects the blank is similar tothathereinbei'ore described. The manner of folding in the said piece 11,will be evident from Fig. 12.

In Fig. 13 a blank is shown wherein the doubling piece is formed in twohalves '6 1', each being one-half of the end of the box and integralwith one of the llaps, g, g, and both of the lines 6, (5, being newscore lines.

Fig. 14 shows how said pieces, t, 'i, are folded in. In all otherrespects the blank is similar to that hcreinbcfore described.

Evidently the cover as well as the box can be made of blanks like thoseshown in Figs. 11, 12, 13 and 14.

Now, having described my improvements, I claim as my invention 1. Aknock-down box and cover, each having side and end flaps adapted to turndown inside the box and cover and extending to the bottoms of the same,andaclampingpieco adapted to clamp said side and end flaps,substantially as described.

2. A box and cover, each having turn-in side and end flaps extending tothe bottom thereof, and a separate clamp piece, engaging said flaps,substantially as described.

3. A telescoping box and cover, each having turn-in side and end flapsand an inside clamp piece of the same finish as said side and end flapsand adapted to clamp the same, substantially as described.

t. In knock-down boxes and covers, and in combination with side and endflaps which will turn in and down to the bottoms of said boxes andcovers, separate bottoms for looking said flaps, substantially asdescribed.

5. In blanks for knock-down box covers the combination with side flapsand turn-in side flaps of holes situated to be bisected by the scoresbetween the said side flaps and turn-in side flaps and so that when thelast named flaps are turned in the halves of said holes will registerand form thumb notches in the sides of the cover, substantially asdescribed.

6. A telescoping box and cover having side flaps, turn -in side flapsshorter than said side flaps, end flaps,inside end flaps narrower thansaid end flaps, turn-in end flaps wider than said end flaps, and aninside clamp piece adapted to clamp said turn-in side and end flaps,substantially as described.

7. A knock down box having turn-in side and end llaps extending to thebottom of the box and showing within the same finish as the exterior ofthe box, and also having a separate bottom adapted to be inserted withinthe box and clamp said turn-in flaps and showing the same finish as theexterior of the box, substantially as described.
